Ishaq bin Mansur al-Kausaj إسحاق بن منصور بن بهرام - الكوسج · The Book of Ghusl and Tayammum

"The Messenger of Allah (ﷺ) said: 'While Ayyub, peace be upon him, was bathing naked, locusts of gold landed on him and he started to collect them in his garment. Then his Lord called him (saying): "O Ayyub, did I not make you rich?" he said: "Yes, O Lord, but I cannot do without Your blessing."

"If any one of you touches his private part with his hand, let him perform Wudu'."
